Entropy shown by heat loss. Entropy is a measure of the amount of order or disorder in a system,as well as how reversible a change is. This is illustrated here by the hot tea (left) losing heat to become a colder cup of tea (right),a process that can only be reversed by adding energy. The tea's energy being dissipated is due to entropy increasing (the second law of thermodynamics). Eventually,the entire energy of the universe will spread out in what is known as the 'heat death' of the universe,a direct consequence of entropy increasing to a maximum | |
